Git Rebase vs. Merge: Which to Choose for Branch Merging?

Git rebase and merge are both tools used for merging branches, but their merging methods and results differ.

Git merge combines changes from two branches into a new commit. It creates a new commit that includes all modifications from both branches, preserving the history of both branches and merging them together.

Git rebase, on the other hand, applies changes from one branch onto another. It rewrites the history of the target branch by placing the changes from the source branch on top of its latest commit, creating a new commit. This new commit only contains changes from the source branch and doesn't preserve the original branch's history.

Therefore, using Git merge maintains branch history but might lead to conflicts. Git rebase helps avoid conflicts but alters branch history. The choice between them depends on specific situations and individual preferences.
